Aimed At Those Who Do Commercial Work

Hi all,

We've been asked by the company who own a small business unit to fit a water ring mains with an inline water filter and 3x isolatable supplies to feed manufacturing equipment. No huge issue there. Why would someone want a water ring mains though? Does it help to balance the flow to each piece of machinery better? I'm assuming it's supplied off one 22mm pipe say and then tees off and runs round in a 15mm ring for example?

Can anyone who has fitted one of these before give me any tips/benefits of their experience or is it really as straightforward as I suggest?

Many thanks.

Got you. Is it as simple as one pipe running into it (suitably sized) then just a ring of pipe of a lower pipe size? Do I need to think about anything else?

Back flow prevention mate.

Sure thing. I will fit a check valve as a matter of course before the ring mains part of the pipework. I would imagine the cutting machines may want one as well, not 100% sure yet but will check.

Be worth checking but like you said you may need them at the point of connection of the machine, worked on a factory who had gate valves as isolation and they all leaked and let by!!
